Work some white-hot highlights.

The trick to Gisele's signature beach-babe hair color is the widely spaced highlights that become brighter and blonder at the tips. "She's got lots of different tones in her hair. The chunkiness of the highlights and the white ends are what create the sun-kissed feel," says her stylist, Harry Josh, who hand-paints Gisele's highlights himself. So next time you sit down for a dye job, take these directions to your colorist. Or, if you DIY your highlights, wipe the formula off each strand very slowly, starting from the top and taking an extra minute or two to reach the ends to bleach them out.

Who doesn't want Gisele's perfectly sexy "I just got out of bed with Tom" unkempt waves? (Some of us might not mind the Tom part of the equation either, but let's stick to hair for now.) Turns out the secret is rolling around in bed! "I tell her to wash her hair the night before an event instead of that morning," says her stylist, Harry Josh. "This way, she sleeps on it and gets a good matted bedhead-y texture." To prepare her hair for an event, Josh uses a —the biggest you can find—on her second-day hair to give it a bit of bend, along with dry shampoo (like ) to give it fullness, adding some on the ends to create a little shine and separation between the waves.

Fashion icon from the'90s Linda Evangelista once said, "I don't get out of bed for less than $10,000," referencing the going rate for her and her supermodel pals. While that's a paycheck we can all lust after, fancy I'm-worth-it curls can be had for the price of a good curling iron. To create Miranda Kerr's flawless curls, David Keough uses a 1-inch curling iron on the back and side sections of her head, holding the iron horizontally, then rolling hair under and around the iron. When he gets closer to the front of her head, he begins to mix up rolling directions—winding the iron up, down, back, forward—so the curls don't look too fussy. The last two sections in front get the classic Farrah Fawcett treatment: Hold the iron vertically and roll away from your face. The final result? A '40s-inspired look that still looks fresh.
